1 KHz would probably be a good point.
If you need a straight tone let me know I can probably get you one today, email me

Thanks for your help Ryan, I found test tones here: http://realmofexcursion.com/downloads.htm

Just to make sure with you, the way to calculate the proper voltage is 140W x 4 ohm load and take the square root of that. I calculated 23.66 V.

If you insist on turning with the higher power then yes thats what it should read.

oh right, you said i might not want to do it at the higher power. What would be a better number?

well, I went and played the test tone at 30 out of 35 (~85%) and decided to measure the voltage at the gain I had already set.. BAM! right on the money at ~21V. Maybe my ears do not deceive me after all! This is probably a good number since it is not the full 22.66V calculated at the full 140W.

Thats roughly 110 WRMS.

22 Volts should yield another 10 WRMS -> 120 WRMS total.
